When the units are used in combination, straightness for SJ-411 / 412 drive unit will be degraded about 0.2 μm.
Cannot be used when the tester’s main unit is an older model (SJ-401 / 402).

 Assessing a single measurement result under two different evaluation conditions
A single measurement enables simultaneous analysis under two
different evaluation conditions. A single measurement allows calculation
of parameters and analysis of filtered profiles without the need for
recalculation after saving data, contributing to higher work efficiency.

3-axis Adjustment Table <Option> 178-047

This table helps make the alignment adjustments required when measuring cylindrical surfaces. The corrections for the pitch angle and the swivel angle
are determined from a preliminary measurement and the Digimatic micrometers are adjusted accordingly. A flat-surfaced workpiece can also be leveled
with this table.

Easily measures R-surface roughness (skidless measurement)

Usually, a spherical or cylindrical surface (R-surface) cannot be evaluated, but, by removing
the radius with a filter, R-surface data is processed as if taken from a flat surface.
Other curved surfaces can be processed besides cylindrical, such as parabolical and ellipsoidal.

Simple contour analysis function

Point group data collected for surface roughness evaluation is used to perform simplified contour analysis (step, step height, area and coordinate
difference). It assesses minute forms that cannot be assessed by a regular contour measuring machine.

Your choice of skidless or skidded measurement

Skidless measurement Skidded measurement
Skidless measurement is where surface features are measured relative In skidded measurements, surface features are measured with reference
to the drive unit reference surface. This measures waviness and finely to a skid following close behind the stylus. This cannot measure waviness
stepped features accurately, in addition to surface roughnness, but range and stepped features exactly but the range of movement within which

*2 This is the lowest position of the standard stylus mounted on the simple column stand.
Since it is 35 mm from the base top, a block of suitable height is required for calibration with
a roughness specimen. Use the stand in combination with optional accessories such as a
leveling table (178-016) or an XY leveling table (178-024).
